Title:
METHOD FOR PRODUCING FLUORINE-CONTAINING DIALKYL CARBONATE COMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2018/097529
Kind Code:
A2
Abstract:
The present invention relates to a method for producing fluorine-containing dialkyl carbonate compounds, which are suitable as non-aqueous solvents for non-aqueous electrolytes used in secondary batteries. When an alkyl chloroformate and an alcohol are reacted in the presence of an ether-containing imidazole derivative base, the reaction can be carried out at room temperature as compared with the prior art, and the products can be separated in a short time from the reactants. This is an economical process and according to the present invention, it is possible to obtain alkyl carbonates containing fluorine atoms simply and without difficulty in the removal of solvents, salts formed during the reaction, and by-products. Accordingly, the production method of the present invention can be effectively applied to the production of fluorine-containing dialkyl carbonates used for various applications such as electrolytes of lithium ion secondary batteries, medicines and fine chemicals, pesticides, polar aprotic solvents, synthetic lubricating oils and the like.
